HANS MUMM, OF LIDGERWOQI NORTH DAKOTA.

GRAIN-SHO'CKER.

Application filed December 6, 1915.

To all whom it may concern Be it known that 1, films MUMM, acitizen of the United States, residing at Lidgerwood, in the county of Richland and State of North Dakota, have invented certain new and useful Improvements in Grain-Shockers, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to harvesting mechanism, and particularly to machines for shocking grain.

he primary object of my invention is the provision of a very simple, easily operated, and effective mechanism adapted to be attached to and moved with a binder on the field, whereby sheaves may be received from the binder plat-form and whereby these sheaves or bundles may be formed into a shock, the shock then deposited upon the ground butt downward. 3

A further object of my invention is to provide a shock former composed of resilient elements curved approximately into the form of the shock, there being means provided whereby the resilient elements may expand as the sheaves are deposited therein and whereby these elements may be compressed to compress the sheaves into the form of a compact shock and whereby the shock former may be turned into a vertical position to drop the sheaves and at the same time opened or expanded so as to permit the shock to drop out.

A further object of the invention is to so construct the former that it may expand equally and not take a flattened or elliptical form in expanding as the sheaves are deposited within it. I

A further object of the invention is to provide means for automatically feeding the sheaves into the former by power derived from the traction wheels of the machine, to provide means whereby the shock compressin the former expanding and the tipping of the former to a discharge position and the return of the formerto its receiving position may be accomplished through the power of the traction wheels, the mechanism being thrown into operative engagement with the traction wheels by means of a hand trip for this purpose under the control of the operator.

A further object of the inventionis to provide means to prevent the tipping of the former while sheaves are being 'dis- Specification of Letters Patent.

charged into the former, and still another 01)]6013 is to provide means for adjusting the former so that it will be disposed in a vertical discharging position whether the machine is moving up and down hills or operating on'si'de hills, this mechanism being automatic in its action.

Other objects will appear in the course of the following description.

Referring to these drawings, it will be seen that my mechanism includes a rectangular frame composed of the side bars 2 upon the rear ends of which are mounted the traction wheels 3. The rear ends of these side bars are connected by a transversely extending beam l forming part of the frame. The extension beyond the side bars 2 and at the other side of the mach ne is connected to a longitudinally extending frame bar 5 which is formed at its rear extremity with an eye (3 whereby it may be operatively connected to a binder. Formed upon this bar 5 is an upwardly extending arm 7 having a forwardly extending portion 8 which is parallel to but above the frame bar 5 and extends beyond the eye 6. Formed upon one of the frame bars 2 is an upwardly extendingmember 9' corresponding to the member 8 but which also extends inward as well as upward. Pivoted to the extremity of the bars 8 and 9 are the rails 10 and 11. The rails are pivoted to the bars 8 and 9 at 12 and extend forward beyond these pivtal points as at 13.

Disposed between the rails is the former A. This former includes oppositely disposed parallel rods 14 and 1 1. To the rod 14 are attached a plurality of arcuate resilient arms or rods 15 illustrated as four in num ber. To the rod 11- is attached a plurality of resilient arms or rods 16 illustrated as four in number, the upper ends of these rods crossing the upper ends of the rods or arms 15. The lower ends of these rods beyond their point of attachment to the member 11 are extended downward and laterally in a curve and below and spaced from the depending ends of the rods 15 and project out beyond these rods in position to receive the sheaves as they are discharged from the binder. The members 16 are also connected to each other by means of a longitudinally extending rod 17 and the members 15 are connected to each other by means of the longitudinally extending rod 18. These rods 14, 14?, 17 and 18 hold the members 15 and 16 in spaced relation but do not interfere with their resilience.

Attached to the rods 16% and projecting laterally therefrom is a shaft or axle 19 which is relatively short, while attached to the rod 1% and extending laterally therefrom is a shaft or axle 20 which is relatively long. It will be noted that the former composed of the rods 15 and 16 is disposed relatively close to the rail 11 and separated more widely from the rail 10. The shaft 19 is rotatably mounted in a boxing or ournal bearing 21 which is slidingly mounted upon the rail 11 but held from lateral movement with relation thereto. Surrounding the shaft 20 is a sleeve 22 which is in turn slidingly mounted in a boxing 23 which has sliding engagement with the rail 10 but no lateral movement relative to the rail, the boxings 21 and 23 following the rail. Thus if the rails are bent inward the corresponding boxing will move inward when it reaches that part of the rail, while if the rail is bent outward the corresponding boxing will move outward when it reaches that part of the rail. The reason for this movement will be hereafter stated.

Mounted upon the shaft 19 and extending upward therefrom is a standard 2 1 and mounted upon the shaft 20 and extending upward therefrom is the corresponding standard 25. Mounted upon the upper ends of these standards are the bell crank levers 26. Mounted upon the upper end of the standard 2 1- is a tubular member 2-7 and mounted upon the upper end of the standard 25 a rod 28 which telescopes within the tubular member 27. From one of the bell crank levers 26 a. wire or other flexible connection 29 extends to the upper end of the standard 24, and from the other end of the same bell crank lover a wire or flexible connection 30 extends to the rod 17 about midway of its length. From the upper end of the other bell. crank lever 26 a like cord or flexible connection 29 extends to the opposite standard, while from the other end of the same bell crank lever a flexible connection 30 extends to the rod 18. The purpose of these bell crank levers 26, the connections extending therefrom, and the telescopic members 27 and 28 is to cause an equal expansion of the arcuate members 15 and 16 as the former is filled with sheaves. The operation of these members will be more fully described later on. Generally speaking, the operation of the parts heretofore described is as follows: At a predetermined time after the former has been filled, the former is moved forward on the rails. It will be noted that the rail 10 is formed with the inwardly extending portion 31 and that the rail extends parallel to the axis of the binder for a certain distance, as at 32, and is then outwardly-bent as at 33. The rail 11, however, has only one bend 33* which corresponds to the bend 33. Now when the former moves forward under the action of the mechanism which will be later described,

the boxing H3 is engaged by the bend 31 and forced inward. This causes the compression of the former and compresses the sheaves contained therein. As the boxings 21 and 23 together with the former move still farther forward the boxings 21 and 23 engage the bends 33 and 33, respectively, and are drawn away from each other, thus expand in the former. At this time the rails 10 and 11 are tilted from a horizontal to a vertical position by a. mechanism which will be later described, and the shock is dropped upon the ground. After the shock has been disengaged the rails are again tilted to a vertical position, releasing the shock and disposing the former in position to again receive the sheaves.

Mounted upon the rear end of the frame formed by the members 2 and 5 is a main shaft 34 which carries the cranks 35 and '36. These cranks are connected by rods 37 and 38, respectively, to the boxings 21 and 23, respectively, and therefore a complete rotation of the shaft 34 will cause the former to move forward its full stroke and then cause the retraction of the former to its normal position. The shaft 34 carries at its extremity the loose sprocket wheel 39, there being a sprocket chain 40 connecting it to a sprocket wheel 41 mounted upon a packer driving shaft 42. This packer shaft carries at its end the gear wheel 43 which meshes with a gear wheel 44mounted upon a shaft 45 which operates certain packing arms as will be later described.

Mounted upon the shaft 34 is a sprocket wheel 46 whichis loose upon the shaft 34 and is driven by means of a sprocket chain 47 from the axle 48 upon which the traction wheels are mounted. This sprocket chain 47 however, may be connected to receive power from the traction wheels in any suitable manner. One end of the sprocket wheel 46 is formed with clutch teeth, and coacting with these clutch teeth is a clutch member 49 slidable upon the shaft 34 but keyed or splined thereto. This clutchinember is moved into engagement with the sprocket wheel 46 by means of a shipper rod 50, this rod being in turn connected to a shipper lever 51mounted upon a bracket 52 on the frame 4. The lower extremity of this shipper lever 51'has attached'to it a rod 53 which eXtends laterally into position to be operated by the binder operator, or this rod 53 might be automatically operated by a trip wheel or other suitable mechanism not shown. The clutch member 49 is urged out of engageinent with the sprocket wheel 46 by means of a spring 54 and the member 49 is held in engagement with this sprocket Wheel by means of a split ring or annulus 55 which is disposed concentric to the shaft-34 and is supported in any suitable manner, this ring having parallel guides 56 engaging with a pin 57 on the member 49. Whenthe member 49 is moved. inward. into'engagement with the sprocket wheel 46 the pin 57 will -move out from between the guides 56 which prevent the spring 54 from returning the clutch 49 to its disengaged position until the clutch has'made one revolution and the pin 57 has again come back to the entrance of the slot between the members 55. Thus the-clutch 49"will be held in engagement with the sprocket wheel for one complete revolution and power will be communicated rom the traction wheels of the machine to the shaft 34 during this complete revolution. Thus during this complete revolution the cranks 35 and 36 will move the former forward to its discharging position and then retract it to its receivingv position.

For the purpose of tipping the rails 10 and 11 upon their pivots .12 to thus cause the rails to take an inclined position in" order to discharge the shock near to the ground, I mount upon the shaft 34 the elliptical gear wheel 58 which in turn engages with an elliptical gear wheel 59 mounted upon a crank shaft 60 supported in, a standard 61 or in any other suitable manner. It

will be seen that these gear wheels are rotatably mounted each at one ofits foci and it will be seen that by reason of using these elliptical gear wheels the speed with which they relatively rotate will be varied and the rotation of one of the gear wheels will be relatively rapid at one point and relatively slow atanother. At the time that the clutch 49 is thrown in the gear wheels will be in the position shown in Fig. 3, and will start at their slowest speed. While at the time that the members 22 and 19 are at the bends 33 and 33 the shaft 60 will be rotating at its highest speed. The crank 61 on the shaft 60 is connected by means ofa rod 62 with a yoke 63 whose two arms extend to a point in front of the former and then eXtend lat erally and forwardand are pivot-ally connected as at 64 to the rear ends of the rails 10 andll respectively, rearward of their pivotal points. It will thus be seen that at the time that the former has been forced forward so that the members 21 and 23 are at the bends 33 and 33 the rails are suddenly tipped from their horizontal'position to an inclined position, and simultaneously the members 21'and 23 move outward under the action of the bends 33 and 33, respectively, thus expanding the former and permitting the shock to drop out. The yoke 68 then moves rearward bringing the rails to ahorizontal position and the former moves back to its normal or receiving position ready for filling.

Thus the operation of setting down the shock on the ground is completed during revolution of the main shaft 34, and on the completion of this one revolution of the main shaft 34 the clutch 49 will automatically slide back out of its engagement with the sprocket wheel 46 and the shaft will be held from any further rotation by the pin 57 engaging between the members This prevents any accidental movement of the shaft 34 and holds the former in its receiving position.

The packing mechanism is as follows: The packing shaft 45 is formed with a plurality of cranks 65, each of these cranks carrying sleeves 66 through which passes the shank or arm 67 of a packer. These arms 67 have outwardly divergent tines 68 at their outer ends and at their inner ends are pivoted as at 69 to a link 70 in turn pivoted to the frame bar 5. These packers move between and on each side of the lateral extensions 16' of the rods 16 and act to force the bundles of grain as they are received from the binder into the shock former. The packer shaft 45 is operated from the packer oriving shaft 42 and the manner in which this shaft is operated is as follows: Connected to rotate with the loose sprocket wheel 39 and mounted upon the sha t 34 is a sleeve 72, which sleeve carries upon it the cam shaped member 73 having clutch teeth 7 4 which engage with clutch teeth on the sprocket wheel 46 but which are normally held out of engagement therewith. The cam member 7 3 has a collar 7 5 formed with an annular groove and engaging this annular groove is an annulus 76 in turn connected to a yoke 77, this yoke in turn being attached to a rod 78 which eX- tends parallel to the shaft 34 and passes through an eye 79 formed in the upper end of the shipper rod 50. This rod 78 is formed with two stops 80 and 81 disposed on each side of the eye 79. The purpose of this rod 78 and its stops will be later stated.

The cam member 73 is normally urged toward the sprocket wheel 46 by means of a spring 82. The cam member is normally held away from its clutched engagementwith the sprocket 46 by means of a stop 83. hen, however, he cam member turns in one direction the shoulder or highest point 84 of the cam will pass the stop and as a consequence the spring 82 will then act to force the cam and the clutch toward the sprocket wheel 46 and force the sleeve 72 into engagement with the sprocket wheel to thus cause the rotation of the sleeve and of the gear wheel 39. This of course will cause a rota tion of the shaft 42, the shaft 45, and the op eration of the packers. This initial sliding rotation of the sleeve 72 in order to allow the highest part 84 of the cam to pass the stop 83 is secured by the fact that the binder pushes a bundle against the packer tines 68,

and this pushing of a bundle against these packer tines will cause a slight rotation of the shaft 45 and of the shaft 42. This will be transmitted to the sleeve 72 which will turn-the cam 73 just sufficient to cause its highest point 84 to pass the stop 83, whereupon the spring will throw the clutch members on the sprocket wheel and the cam into engagement with each other. When the cam 73 is in clutched engagement with the sprocket wheel 46 the sleeve 72 will make one complete revolution, or until the edge of the cam by its engagement with the member 83 has forced the cam back out of its engagement with the sprocket wheel. lit this time the cam plate 85 which is mounted upon the sleeve 7 2 will contact with the spring 86 which is mounted in any suitable manner and which holds the sleeve 72 from any further accidental rotation until the sleeve is again actuated by the pressure of bundle on the packer tines 68. l vhile the shock former is in operation, however, that is, to complete the shock, expand, dump the shock and return to its original position, the packer tines 68 are turned back below the rod 68 by the engagement of a slidingly mounted plate 87 with an arm 88 which prevents a rotation of the sleeve 7 2 which will release the cam 73. This plate 87 is mounted in guides 89 supported in any suitable manner upon the frame of the machine is shifted by means of a rod 90 connected to the upper end of the lever 51. When, therefore, the lever 51 is moved by mea is of the connection 53 to shift the clutch 49 into en gagement with the sprocket wheel 46 the slide 87 will be shifted to the left in Fig, 1, and will be in position to engage the arm 88 and prevent any rotation of the sleeve 72. Immediately, however, that the clutch 49 flies back under the action of the spring the slide 87 will be moved out of the way of the arm 88.

Tn order that the shock shall be discharged from the former it is necessary that at the time that the rails are tipped downward the former should be rotated through approximately 90 so as to carry the forward end of the former downward toward the round. As will be noted, the shaft 19 is freely'rotatable with relation to the boxings or bearings 21 and 23 and therefore it is necessary to provide means for positively rotating this shaft and rotating the former with the shaft as the boxings 21 and 23 move forward under the action of the cranks 35 and 36. To this end I mount upon the shaft 19 the arm 91 connected by a link 92 to a rod 93 extending to the front of the machine. A joint breaking arm or strut 94 is also rigidly connected to arm 91 at an angle of approximately 45. The free end of this arm is crotched or bifurcated, as at 95, to engage with arm 93 for a purpose which will be later stated. WVith this construction, as the shaft 19 moves forward under the action of the cranks and 36 the rods 91, 92 and 93 will move from the position shown in full lines in Fig. 13, thus rotating the shaft 19 as illustrated in dotted lines in Fig. 13 to a position where the shock may be discharged.

It will be obvious that means must be provided for discharging the shocks in a vertical position both when the machine is moving up or down a hill and when the machine is operating on a side hill. Unless this means is provided the shock will be discharged at an angle to the vertical. Then the machine is-moving down hill and the shock former is moved to a dumping position, the shock former comprising the memhere 13 and 16-n1ust be tilted to such a posi tion that the axis of the shock is at an obtuse angle to the plane of the forward portion of the machine, and when onthe other hand the machine is moving up hill the shock former must be tilted to a position where its axis is at an acute angle to the plane of the machine.

The mechanism now to be described operates to increase the tilting movement of the shock former in one place to an amount greater than its normal tilting movement and decrease it in the other case to an amount less than its normal tilting movement. To this end, at the rear of the machine there is mounted a standard 96 supporting at its upper end the pivoted balance bar 97 having a downwardlyextending finger 98 disposed immediately beneath the pivot and extending radially relative thereto. Also pivotally mounted upon the standard 96 is an arm 100 carrying a yoke 101. Pivotally mounted upon the ends of the yoke are the bell crank levers 102 and 103. The upwardly extending arms of both bell cranks are connected to the rod 93. The fin 'er 98 normally extends downwardly in a plane immediately between the arms of the yoke, as illustrated in Fig. 13, but the lower end of the finger when the former is in its receiving position is disposed above the plane of the horizontal arms of the bell cranks.

Below the arm 100 is a cam 104 which is mounted-upon the shaft 30 which reciprocates the hearings or boxings 21 and 23. WVhen the former starts to move forward and the links and rods 91, 92 and 94 initially start to rotate the shaft 19, the cam 104 engages the arm 100 and lifts the yoke 101 upward. If the machine is on level ground the balance bar 97 willbe parallel to the arms of the bell cranks 102 and 103 and the finger 98 will be disposed between the ends of the bell crank. When the arm 100 rises therefore under the action of the cam, the finger will pass between the arms of the bell cranks and will not affect these bell to the plane of the machine.

cranks and a normal rotation of the shock,

former will be secured. l/Vhen the machine is moving up hill, however, as illustrated in Fig. 14, the finger 98 will be disposed over the armof bell crank 102 and when the yoke rises under the action of the cam the finger will engage the bell crank and tilt it in a direction to shift the rod 93 rearward, which, through the link 92 and the arm 91 will rotate shaft 19 sufficiently less than its normal amount of rotation so that the axis of. the shock will be at an acute angle to the plane of'the machine. 011 the other hand,

when themachine is running down hill the finger 98 will engage with the bell crank 103 which will increase the movement ofthe shaft 19 to an amount greater than 90 and the former will=be held at an obtuse angle In other words, the action ofthe shock leveling device illustrated in Fig.:13 is to in one case increase the angular movement of the shock former and in the other case decrease such angular movement.

would not give suilicient .rotation to the shaft 19 and further would cause the arm 91 to move to a dead center when the rod 93 was in either of its extended positions. 1 'By providing the link 92 and providing the crotc-hed arm 94, I secure a much greater angular movement of the arm 91 and obviate the dead-centering of this arm 91. As the rod 93 moves forward, the arm 91 will: move upward and the arm 94 will move downward, but on a reverse movement of the rod 93 the arm 91 will move downward, the arm 94 will engage at the joint of the rod 93 to the link 92 and will cause thelink 92 to take an angular relation to the rod 93 and the force applied by the rod 93 will be applied to the arm 94 to rotate the shaft.

Preferably and inorder to prevent the rod 93 and the link 92 from dropping downward when the link 92 and the rod 93 are in alinement with each other, I pivotally connect the'rod93 to'the link 92, asat 105, and provide the finger 106 which is attached to the link 92 and extends over the joint and is adapted to engage with the rod 93 and prevent any descent of the link '92 and rod 93 atthe joint, as shown clearly in,

Fig. 14.

The rod 93-must be held from any undue forward or rearward movement which would tend to cause the shock former to oscillate accidentally, and to this end I .111 acts to draw the arm against the seat 109. Now, movement of the rod 93 either forward or rearward from this normal position will tend to expand the spring 111. The rearward movement of the rod 93 will lift the arm 110 from the inner seat 109 and cause the arm to fulcrum upon the outer seat 109 which will expand the spring. A forward movement of the rod 93,

however, will cause the rod to bear upon the inner seat 109, raise it from the outer seat and thus expand the sprin Thus this spring 111 will yieldingly resist any accidental longitudinal movement of the rod 93 and therefore resist any accidental rota tion of the shaft 19 and of the former thereon.

The mechanism for causing the shock former to be disposed in a vertical position when the machine is running along the side hill operates on the same principle as the parts 97 to 10-1. As will be seen, the rail 11 is in two sections a and Z), the joint of this rail being designated 113. The hinged connection of the two sections is disposed to one side of the rail by the formation of laterally projecting arms hinged to each other, as at 11 1 (see Fig. 21), and this is done so as to permit th bearing or boxing 21 to move over this joint with ease. Because of the hinged joint in the rail the section a can move to a greater amount or farther than the section b. Thus when the rail 11 is tilted to a position to discharge the shock the lower end or section of the rail can move to a greater or less angle to the horizontal than the upper section of the rail. A spring arranged as will be later described, yieldingly holds both sections of the rail in alinement so that both sections will normally rise together. Under normal circumstances, when the rails 10 and 11 are tilted by the yoke 63 and the allied parts the two sections a and b of the rail will have the same angle and be in alinement with each other as seen in Fig. 13. When, however, the machine is running over a side hill, the level adjusting means now to be described will cause the section a to either be accelerated or retarded in relation to the section b.

In order to cause this acceleration or retardation of the movement of the section a of the rail 11, 1 mount upon an upward extension 115 of the support 9 an arm 116 upon which the balance bar 117 is pivotally mounted. This balance bar has the downwardly depending finger 118 disposed radially upon the axis of th balance barQ Extending laterally from the rail 11 rear ward of its joint 113 is an arm 119 carrying at its extremity a yoke 120. To the ends of this yoke are pivoted the levers 121 and 122. The lever 121 is pivoted intermediate its ends, while the lever 122 is pivoted at one end. Attached to the section a of the rail forward of its joint and of its pivot is a forwardly extending arm 123 to the extremity of which the lever 121 is connected by a link 12 1, the link being attached to the outer end of the lever. A link connects the inner end of the lever 122 to the end of the arm 123.

If now the machine is operating on a side hill which causes the traction wheels 3 to be raised above the level of the harvesting machine, the balanc bar will cause the finger 118 to be disposed over the lever 121. Now when the rails are tipped to an inclined position by the action of the yoke 63 the rail 11 forward of its pointof pivotal connection to the arm 9 will rise, and the rail rearward of its pivot will move downward. Under normal circumstances and when the machine is operating on the level,

i the rise of the forward end of the rail will carry the yoke upward and the finger of the balance bar will pass between the ends of the bell crank levers 121 and 122., but if operating on the side hill inclined downward from the traction wheel 3, the rise of the forward end of the rail 11 will carry the lever 121 against the finger of the balance bar, actuating or depressing the lever 121 and thereby raising the arm 123, which, as it is connected to the rail section a, will cause the relatively upward move ment of the rearward section a of the rail. This causes the section a to be disposed at an angle to the section b so that when section a of the rail is at an angle of 1-5 to horizontal the section a will be at a greater angle. The rail 10 will of course have exoouted the sa1ne movement as the rail. section 5 and therefore the rail section a will be at a greater angle to the horizontal than the rail 10 and this will allow that side of the shaft 19 toward the hill to slip down lower than the boxing or bearing 23 to cause the former to be disposed. in a vertical position. If the inclination of the hill is such that the traction wheels are disposer lower than the harvester side of the machine, then the finger on the balance bar will engage lever 122 and as a consequence the section a of the rail will be retarded in its movement relative to the section b of: the rail and relative to the rail 10 and the rail 10 will move farther than the rail section a and as a consequence the boxing or bearing 23 will shift downward below th boxing or bearing 21.

The mechanism used for the purpose of supporting the rail sections a and 6 yieldingly in alinement with each other under ordinary circumstances is illustrated best in Fig. 20, and is analogous to the means for holding the rod 93 from vibration. The rail section Z) has extending from it adjacent the joint an arm 126 which is rigid with the rail.

The rail section a has extending from it an arm 127 and an extension 128 pivoted to it. This extension may move outward, that is, away from the arm 126, but cannot move inward beyond a position in alinement with the arm 27 by reason of the stop 129 which is attached to the section 128 and extends over the joint between the sections 127 and 128. Attached to the arm 126 and extending at right angles thereto is a stop member 130 and connecting the arm 126 to the extension 127 and arm 128 is a coiled contractile spring 131. The operation of this is that when the rail section a is bent downwardly with relation to the section Z) the arms 126 and 127 are bent into conver ing relation but the extension 128 will stri e the stop 130 and be forced outward, thereby thus expanding the spring as illustrated in Fig. 20. When, however, the rail section a is turned upward or outward with relation to the rail section Z) then the arm 127 and the arm 126 are turned into diverging relation. The extension 128, however, isheld from any movement and also shifted into a divergent relation to the arm 126 when the spring 131 is expanded. Thus the spring 131 normally acts to hold the sections a and b in alinement with each other but permits the yielding movement in either direction. V

In F igs. 1 to 20, for the sake of simplicity and to avoid confusion, I have illustrated the bearings 21 and 23 as being in the form of boxings embracing a single rail 11. In actual practice, however, this construction would prevent the easy movement of the boxings or bearings upon the rail and therefore 1 preferably form the rails in three sections, as illustrated in Fig. 22. Only one of these rails has been shown in these sectional views, the rail 11. These three sections comprise the base member 132 and the two angular members 133 and 134, these angular members being spaced above the base member and also spaced from each other, the boxing which is designated in this case 21 resting upon the base member 132 of the rail to slide therealong and is held from lateral movement and is guided by the members or sections 133 and 134, the boxing having an upwardly extending pin 135 which engages between the members 133 and 134. Thus the boxing is held firmly supported but is guided by the rails.

The general operation of my mechanism 'is believed to be obvious from the description heretofore. The former, comprising the rods 15 and 16, when it receives the bundles of grain, is in the position shown in Fig. 4 and in full lines in Fig. 1. In this position the former is expanded and the packing members 67 are being operated across the bundles of grain into the former. hen the former is filled the operator pulls upon the rod 53. This engages the .clutch member 49 into engagement with the clutch member 46 and at the same time disengages packer shaft 42 from operative engagement with the sprocket wheel 46. The cranks 35 and 36 noW push the former forward upon the rails 10 and 11 and this actsto compress the shock former so as to shape the shock and then as the sliding boxingsthe position shown in full lines to the posi-.

tion shown in dotted lines and the shock will be deposited upon the ground. As soon as the shock is discharged the rails are tipped back to their horizontal position and at the same time the boxings or bearings 21 and 23 are drawn forward on the rails to the position shown in Fig. 1 and this action of course causes the former to tilt back to its original receiving position. As the former moves toward the forward ends of the rails the bearing boxings 21 and 23 will move laterally to expand the former to its receiving position. The bell cranks 26 with the connections 29 and 30 act to cause the rods or bars 15 and 16 to expand uniformly and not merely laterally. The mechanism as shown in Figs. 13 to 15 and 17 to 20 will cause the shock always to be deposited in a vertical position without regard to the lateral or longitudinal inclination of the ground.
